When the first magnetic element 20 is on the inner wall surface of the refrigerant circulation flow path 50 or on the first filter element 60 or the second filter element 70 due to the low bulk density, the accumulated volume of the first magnetic element is large, the refrigerant can pass through The through holes 201 continue to flow in the refrigerant circulation flow path 50 .

Optionally, the number of through holes 201 on the same first magnetic element 20 is multiple, and at least two through holes 201 of the multiple through holes 201 have different extension directions. In this way, when one of the through holes 201 is blocked by the other first magnetic elements, the refrigerant can also flow through the other through holes 201 .

Optionally, the shape of the first magnetic attraction member 20 may be various shapes such as a rectangular parallelepiped shape and a cylindrical shape. The foregoing description and drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The examples represent only possible variations. Unless expressly required, individual components and functions are optional and the order of operations may vary. Portions and features of some embodiments may be included in or substituted for those of other embodiments. Embodiments of the present disclosure are not limited to the structures that have been described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
